Extra Brushless Motor cooling

[t-maxxracer32]

thas pretty creative.

very smart.

if it works.

would gearing it diff help with the heat issues?

or is it just too much volts for the motor?

Hey sike, looks interesting. I had an issue with my hacker maxx today, blew out one front driveshaft. So it was technically rear wheel drve only. Not as much fun, but it did lower my motor temps at least 15 deg, maybe more.

Not sure if that info is useful or not. It would be nice to have a servo selectable 4wd, I do not need 4wd all of the time, but it is nice to have sometimes. I wonder how we could do that with the new emaxx tranny? Spilit the output shaft and make some sort of sliding coupler?

Now that's an interesting proposal. I've never really thought about it.

Hmmm,........I wonder if there's a way to split the tranny output shaft, drill each half for a pin to keep the two running true. Then use a shift fork to Engage/Disengage the front end through the remote?

Let me think about this. LOL

It does sound feasible.

You know that might be in interesting thing to come up with. But tell me.........when is it that you DON'T need four wheel drive?

Fast running on smooth surfaces does not really require 4wd. I have an old emaxx that is 2wd and is super fun to bash with. It does tricks well and will wheely till the batteries die. Plus I get better run time than with 4wd on the smae batteries, and I can use a l can motor instead of an xl and it will stay cool.

Well I got the fans all hooked up to the BEC.

I'll try it again tomorrow on 5S if the weather works with me here.

All rainy here.

Hi T maxx,

Well thanks.

Ummm, yes and yes. LOL This motor isn't rated for this many volts, But I feel like 5S is right at the limit for this setup. By providing some additional cooling, I hope to swing temps back the other way.

I could gear down, but things are in the fun zone now! LOL

This setup rocks on 4S with temps staying in check, but is even better on 5S.
